to build the house of God

22:2 to build the house of God. David’s desire to build a temple already had been commended by God, but He had told David that it must actually be built by his son (I Chronicles 17:2,11,12). David’s experience at Ornan’s threshing floor, where God’s angel had been about to destroy Jerusalem, and where David had offered his repentant sacrifice, convinced him that this spot (where Abraham had long ago offered Isaac) was where it should be built.
